A Duncan man faces prison if convicted of causing a deadly crash along a Canadian County roadway.

Jimmy Dwayne Grissam, 37, was charged May 20 in Canadian County District Court with first-degree manslaughter.

Prosecutors allege Grissam was driving intoxicated and speeding when he caused a fatal traffic collision April 29 along State Highway 152 and Banner Road in Union City.

The defendant was driving a 2004 Ford F-150 south on Banner Road at about 96 miles per hour when he allegedly ran a stop sign at Hwy 152. The speed limit is 55 mph.

After driving his pickup through the intersection, Grissam allegedly crashed into a westbound Ford Escape driven by Kasey Working, 30.

TEACHER DIED AT SCENE

Working, an elementary school teacher in Mustang, was killed in the crash.

Officers, firefighters and medical personnel at the scene reported a “strong possible odor of alcohol emitting” from the Ford F-150 driver, according to a probable cause affidavit signed by Union City police officer Brandon Owens.

Union City Police Chief Richard Stephens offered condolences to Working’s family and friends, calling the incident “a tragedy for everyone involved.”

After being treated at a local hospital for injuries sustained in the wreck, Grissam was booked at 10:38 a.m. May 11 into the Canadian County Jail in El Reno on complaints of first-degree manslaughter, driving under the influence of intoxicants and failure to yield at an intersection.

A preliminary hearing conference for Grissam is set 9 a.m. June 25 before Special Judge Charles Gass.
